N2576S

NIKO-SEM 52 KHz 3A Step-Down Switching Voltage Regulator (SVR) FEATURES N2576 TO-263, TO220 GENERAL DESCRIPTION The N2576 Series switching voltage regulators (SVR) are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, B o t h s e r ie s a re ca p a b l e o f d r i v i n g 3 A load respectively with excellent line and load regulation. The N2576 Series SVR include a switching regulator and compensation network all within the same package. Just add a choke, www.DataSheet4U.com catch diode and two capacitors to obtain an efficient DC-to-DC converter. The output switch includes cycle-by-cycle current limit -ing, as well as thermal shutdown for full protection under fault conditions. The N2576 Series SVR offer replacement for popular 3 terminal linear regulators by providing higher efficiency with reduced heat sink size. In many applications a heat sink will not be required. z Pin compatible with industry products of LM2576 Series z Adjustable output versions z Wide output voltage range, 1.23V to 27V for adjustable output version z DC-to-DC buck converter requiring only 4 external parts z 52 KHz fixed frequency internal oscillator z TTL shutdown capability, low power stand -by mode z High efficiency z Uses readily available standard inductors APPLICATIONS z Simple high-efficiency step-down (buck) regulator z Positive to negative converter (Inverting Buck-Boost) z Isolated Fly back Converter using minimum number of ...
